In this paper, the effects of sleeper size on the cyclic deformation properties of railway ballast under the cyclic loading are discussed. The two-dimensional linear elastic FEM analyses were performed in order to investigate the effects ofsleeper size on the stress distribution in the ballasted track. Based on the results of FEM analyses, a series of full-scale cyclic loading tests using the various sleepers changed the length and height were performed. It is found that the track settlement in the state where a clearance gap is between the sleeper and the railway ballast can be explained the displacement amplitude and the maximum sleeper displacement speed up to the touching.
